Abstract

Изобретение относится к способу кузнечной сварки труб, прутков, стержней и других осесимметричных профилей встык. Согласно предлагаемому способу формуют торцы профилей путем пластической деформации и/или обработки металлов резанием таким образом, что получают уменьшенное поперечное сечение или толщину; выполняют местный нагрев торцов профилей электромагнитным способом за счет индукции и/или прямого высокочастотного электронагрева; и сжимают вместе торцы профилей. На этапе формования одному из профилей придают форму двухарочной кривой. Другому профилю предпочтительно придают выпуклую форму.The invention relates to a method of forge welding of pipes, rods, rods and other axisymmetric butt profiles. According to the proposed method, the ends of the profiles are molded by plastic deformation and / or metal cutting in such a way that a reduced cross section or thickness is obtained; perform local heating of the ends of the profiles by the electromagnetic method due to induction and / or direct high-frequency electric heating; and squeeze the ends of the profiles together. At the molding stage, one of the profiles is shaped into a two-arch curve. The other profile is preferably given a convex shape.
